Working Theory

If you’re looking for pony without negatively affecting the environment, you should look into a Volkswagen Passat free flow catalyst. Installing a high performance catalytic converter is one of many measures a car enthusiast will take to increase exhaust flow and thus gain additional HP. During the past years, developments in metallurgy and chemistry have enabled us to create high flow converters with awesome pony and durability. performance cat converters increase the engine performance throughout the rotational speed range. engine performance-gain is most notable at the wheels and also becomes exponentially larger as further modifications are made to the power train, such as cold air intake, remapper chip or a catback exhaust system. Get rid of restrictive factory Volkswagen Passat catalytic converter that robs you of engine performance

Will the check engine light be triggered?

No, by any means, if catalyst is installed to the factory exhaust system then such an exhaust alteration made to the system would not cause the engine to run lean.

Contrary to the popular belief, catalytic converters are not commodities. There are huge differences in quality between brands, which results from the different raw materials that are used, manufacturing technology, coating materials, and numerous other factors. It is generally reasonable to assume that cheap cat converters are of lower quality, but that doesn't mean that the most expensive catalyst converters are the best. Torque in general, the power you feel in the seat while driving. Magnum Volkswagen Passat performance cat converters increase this torque as well as the pony throughout the entire RPM range. As with performance capability, the current increase isn't anything incredible, but the massive gains tend to improve as the rest of the car's output. Magnum high flow catalytic converters feature engine specific gas restriction and vehicle specific inlet / outlet diameter. Your Volkswagen Passat performance catalyst will fit to factory piping. MIG/TIG/Flux required welding though. The improvement in technology in this industry has led to tuning brand companies being able to offer high flow cat converters that comply with the emission control regulations and bylaws in most of states and countries. Magnum cats will clean as well, if not better, than your stock cat.

These Volkswagen Passat high performance catalytic converters are built with both power output and noxious fume in mind. Inside, our Volkswagen Passathigh flow cats are made with enormous ceramic substrates coated in maximum precious metals. Our manufacturing technology helps to strip out the more noxious fumes without employing undue restrictions like the factory catalysts. Internal catalyst’s honeycomb ceramic substrate maximizes the exhaust flow surface area for significantly reduced restrictions. While at first glance this cat converter looks like any other catalytic converter on the outside, the major difference is hidden in their bellies. Instead of being clogged with large restrictive honeycomb substrate, our low-restriction media gives the exhaust a clear path to your tailpipe. While noxious emission is neutralized, your power needs are totally satisfied.

A Volkswagen Passat performance converter from Magnum puts an end to the noxious fumes that spew from your exhaust tailpipe and, compared to a factory restrictive cat converter, it boasts HP boost and fuel mileage increase. All of our Volkswagen Passat catalytic converters are made to deliver maximum performance potential. A restrictive stock catalyst not only creates harmful vapors, but it robs you of power. Our Volkswagen Passat performance cat converters run more efficiently than factory equipment catalysts and meet smog requirements for squeaky clean emissions in most countries and states (excl California). Get rid of your performance stealing OEM cat converter and its harmful vapors today. You can have this converter for a fraction of the dealer’s price you’d pay if you bought the stock equipment cat.

Check out Magnum diameter specific high flow catalytic converters Additional technical background information Harmful compounds emitted by a 4-stroke engine The ideal combustion exists only in principle. An Otto-engine's efficiency is not better that 30 up to 45 %. Engine's efficiency and the amount of harmful emissions varies on several factors are related to the combustion taking place in the chambers. The theory described with chemical equation:

Ideal perfect combustion

CnH(2n+2) + O2 --- CO2 + H2O

Realistic combustion

CnH2(n+2) + O2 --- C + H2 + O2 + CO + CnH(2n+2) HC

Since the gas is polluted

N2 + O2 NOx

Pollution, additives

S + O2 SO2 + H2O + H2SO3 The carbon-oxide, nitro-oxides, hydrocarbons and the sulfuric-acids are deemed harmful, therefore their emission level is restricted by emission regulations in most of the countries. For over 30 years the most effective way to reduce the emission of harmful gases and materials to clean and neutralize the combustion products subsequently has been to purify the exhaust gas with one or more catalytic converters fitted on the vehicle's exhaust system.

Oxidation and Deoxidation within the catalytic converter

CO + (1/2)O2 --- CO2 CnH(2n+2) + O2 --- CO2 + H2O NOx + CO --- CO2 + N2 There is many other chemical reactions take place. When it comes down to attain the lowest emissions, electronic control over these chemical processes is a must. In modern engines catalytic converters are controlled electronically by exhaust oxygen sensor.

The oxygen sensor

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sonda or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

not sneeze at this economy

Granted I purchased this Camaro used, the EPA highway estimate was 14 mpg, but on a recent trip after having cats welded on, I ran over 16 mpg consistently! For a 7 year old car with 160K miles, I will not sneeze at this economy! So far, so good

engine sounds and runs better

Magnum is a well trusted name in the tuning world. I had used their products in the past and decided to use one of their weld-on fit high flow converters on my Interpid 3.2. Fit is perfect once you have a good welder and a sawzall with a hacksaw blade sped up the removal. After replacement engine sounds and runs better. Overall I am very pleased with this converter.

The converter fit as described, and ive seen notable change of mid range power and a subtle improvement in mileage. My only critique is that as some have stated this is not bolt-on so you have to seek a certified exhaust fitter. In any other respect this is a real performance converter.

great fit at a great price

Product they delivered was as advertised however the shipping took long. I think this might be due to the holidays. FYI the shipping is free but there is no expedited ship option. Overall this catalyst has great fit at a great price! I will buy from magnum again.

engine is notably faster

I chose this converter because it was priced lower than local stores. They shipped the product promptly and fit was great. Better then stock. I wasn’t much concerned with performance but engine is notably faster and responds better. No installation problems what so ever. Buy This Product with confidence.
